Figure 3.

Persistence of populations in the arid and semiarid regions. Median persistence (yr) was observed in isolated 25 × 25 cm2 populations. Small numbers represent the lower and upper quartile if persistence of one or more populations was <30 years. Simulations were stopped after yr 30. Colour code: orange: 10–15 yr, yellow: 16–20 yr, pale green: 21–25 yr, light green: 26–29 yr, dark green: 30 yr.
